RE: Luminosity ratio question on images

Yes, thanks Gregg. We have the alt text that already reads out the inscription on the medal on the primary page that each CTA link points to, but containing alongside isn't something I thought have, perhaps as a caption to the image for low-sighted users to benefit (as well as people relying 100% on screen readers)?

Thanks for your feedback, it's very helpful to have a sounding board.

Kind regards
Louise

Ah

Good catch David.   You should also provide any important text on the image - that is low contrast - with text alongside as well.

I think you need to include the engraved text next to the image, in the primary content of the web site. That's effectively what people who sell commemorative coins, etc., do in their print advertisement.

Incidentally, even without contrast problems, you cant easily rotate desk top screens to read around the edge of the disk, which makes some difficult to read because of the varying angles of the text.
